Sometimes very small additional reinforcement is required in raft basic additional reinforcements. For example, the required Ace = 1.18 comes out, the program beats 12/20. Thus, the current Ace = 5.65. Can we get the reinforcement range above 20 here? For example, if we correct it as 12/30, the current Ace=3.77 decreases and the number of bars decreases. As such, I think it will significantly affect the quantity in large projects.
